A word on VPS CPU mining. Find yourself a free trial account and get that XMR...
I was able to get the first cryptocurrency scam taken down from its VPS.

Do you mean theoretical transactions or actual transactions ? BCH may support more TPS theoretically but almost nobody uses it, so the actual TPS is a lot lower. Besides TPS isn't the whole of the story, I could invent my own coin that could do billions of TPS, but nobody would use it to send large amounts of money because the proven security and trust isn't there. What really counts is the total value transferred per second. Is there any other with a higher VPS (value per second) than bitcoin ?
I run a (new) public node on a VPS that came up last weekend. Its incoming traffic has been a fairly constant 10-12 Mb/s with light CPU use. It certainly has room to grow. Granted that’s a single datapoint, but it’s better on resources than I was expecting.
Is it profitable to run a bitcoin node on a VPS ????
That's because you're only considering the internal hashpower. Your "absolute" hashpower is also "relative" to what it represents in worldwide available compute power. By your metric 100 000 nodes in VPS instances with almost null hashpower would have a better coefficient because "more nodes". If tomorrow half of Bitcoin miners decided they wanted to mess with Litecoin or BitcoinCash then how would your "Nakamoto coefficient" prevent that ?
Posting one address is bad for privacy. Someone can track all of your txns, and also your customers previous history. For very simple setups, Breez wallet has a nice Point of sale feature in their app, and pheonix wallet is good for self custodial lightning. Both of those wallets offer lightning txns for your customers, but can also do on-chain. If you are really getting into accetping bitcoin at your store, you need to setup a BTCpay Server. It's an open source bitcoin merchant setup and its amaizng. You can run for $20 a month on a VPS, or run it at home for free. But you have to expose your IP address if you have it at home for your customers to see. Feel free to hit me up with any questions if you need help!
Bitcoin was never anonymous. People can use it however they want. Some keep it untouched, some spend it on gift cards, VPS, VPN, donations, etc. They can also sell it for fiat and improve their lifestyle. What are the doubts again?
